Pythagorean Astronomy: TRAPPIST-1 and other stories

At the end of last month, there was a lot of interest in the discovery of seven roughly Earth-sized planets in the TRAPPIST-1 system. One month on, Chris North and Edward Gomez discuss the implications of this discovery. We also get an update from the Amaury Triaud, of the University of Cambridge, about TRAPPIST and its successor, SPECULOOS.

Here in our own Solar System, there’s the discovery of a cometary landslide from Rosetta, a milestone in wheel-wear on the Mars Curiosity Rover, and an update on some of Saturn’s darker rings from Japan. Further afield, a study of the rotation of galaxies in the distant Universe came under some scrutiny, shedding a bit of light on the process of scientific discovery.
